is a fragmentary side elevation of a he hottle carrying the cap in dovertical section applied thereto. 3 is an enlarged fragmentary portion ie cap showing the tab heing opened, and, l is a fragmentary sideelevation of the cap showing the tah extended.

ln the drawings wherein for the purpose of lustration is shown thepreferred em hodnnent of my invention, 5 indicates generally the bodyportion of the cap which conof a relatively flat round crown 6 fromwhich depends an annular flange 7 formed with n series of crirnps 8around the lower edge of the flange '3' These crimps 8 frictioncllyengage a semicircular, recess 9 at the upper end of the neck ll) of abottle.

it is a top plan view of the cap in On the diametrically opposite sideof the crown 6 there are slots 11 in alineinent with each other andthese slots are located in the margins of the crown. The slots extenddownwardly through the flange and the crimps 8 and terminate on a linewith the lower edge of the crimps 8. @n the diametrically opposite sidesof the flange 'i there are a pair of tabs 12, which when the tah isinserted on the neclr of the bottle, are hent to the osition shown in 2of the drawings. llhere the tahs 1?; merge, with the crimps 8 on theflange if, there a line of per forations or scorings 13 that intersectsthe lower edge of the slots 11 at right angles. The slot ll is in thecenter of the line of perforation l3.

llhus it will he seen that when it is desired to open the bottle, thecapslQl are pulled outwardly from the position shown in 9 which willbend the tab across the line of perforation. Further movement from theposition shown in Fig. 3 0f the drawings will cause the break along theline of perforation and allow the parts of the tabs on the oppositesides of the slots 11 to spread apart whereupon the cap can he removed.

On the inside of the crown 6 of the hody portion is a. disk of cork 14that bears against the upper edge of the neck 10 of the loottle to makean airtight closure therefor.
